Research on Occupant Evacuation Simulation during Civil Aircraft Emergency

Abstract

Abstract In order to simulate aircraft evacuation process vividly in the 90s certification trials, the influence elements of occupant evacuation during aircraft emergency need to be analyzed. These elements were achieved as evacuee element, aircraft type element, and aircraft external environment element. The three elements were consisted of several factors respectively. In evacuee element contained individual physiological factor and psychological factor, the diversities of individual behavior were discussed in the three escape stages. These factors were applied to cellular automata theory. Then, the cabin environment model was established according to the characteristics of occupant movement during emergency evacuation, and the non-wing exit escape time model was built through a self-designed jumping slide experiment. This research took B737-800 as the experiment prototype and developed the simulation software (EES-air) based on the above models and the existing research results. Three distribution plans of occupant evacuation in cabin area were designed in the simulation software. The simulation results were analyzed from the evacuation efficiency, the number of escape at different time, and the available exit utilization rate. The research results could provide strategy and guidance to emergency evacuation and emergency training for airline.
